Robotic Mitral Valve Surgery

Growing interest in minimalizing surgical trauma during heart procedures stimulated the development of robotic mitral valve surgery in the late 1990s. Initially, the new technology was slowly adopted in clinical practice. However, following encouraging results by teams that adopted robotic heart surgery early on, a growing interest in implementation of robotic mitral valve surgery has emerged. Of importance are the technical developments and possibilities that accompany robotic surgery. Robotic arms feature unique characteristics, allowing unparalleled range of motion and allowing complex mitral valve repair techniques to be performed without limitations related to limited surgical incisions. High-quality three-dimensional vision effectively compensates for the lack of tactile feedback. Several technical solutions have been developed to facilitate mitral valve repair in minimal invasive setting, including chordal guiding systems, now available with various annuloplasty rings. On the other hand, precise vision and movements allows accurate determination of the length of implanted neochordae, facilitating precise determination of the length of implanted neochords even without the use of chordal-guiding systems. With robotic mitral valve surgery, leaflet resection techniques can be performed without limitations, ensuring that no compromises of the surgical strategy are made. Nevertheless, careful preoperative planning with appropriate work-up and imaging is of utmost importance to prevent complications. Moreover, the drawbacks of the initial learning curve and higher procedural costs are counterbalanced by less surgical trauma, lower utilization of blood products, and faster patient recovery. Robotic mitral valve surgery is still a young field and evolving technology that is bound to become an important tool in the toolbox of surgical mitral valve approaches.
